Risk identification method and system based on power grid maintenance plan

The invention relates to the technical field of power grid data identification, and discloses a risk identification method and system based on a power grid maintenance plan, and the method comprises the steps: carrying out the word segmentation of a maintenance text in a power grid maintenance plan list, extracting keywords from a plurality of fields, and obtaining a risk identification result based on a preset matching rule; and quantifying the plurality of risk equipment hazard indexes and the plurality of risk probability indexes according to the keywords, performing weighted calculation on the plurality of risk equipment hazard indexes and the plurality of risk probability indexes to obtain an equipment hazard value and a risk probability value, and performing weighted calculation on the equipment hazard value and the risk probability value to obtain a risk risk value. Therefore, the risk identification efficiency and accuracy of the power grid are improved, and the operation safety of the power grid is g
